Press release: "In the wake of revelations that the Bush administration authorized the warrantless surveillance of U.S. citizens in 2002, the National Security Archive reposted its National Security Agency Declassified electronic briefing book, first published in January 2000 and updated as recently as this year. President Bush's recent admission that he authorized the National Security Agency (NSA) to eavesdrop on U.S. persons without obtaining a warrant has focused the nation's attention on the authorities and regulations governing this sensitive issue. The Foreign Intelligence Surveillance Act (FISA) specifically prohibits domestic surveillance by the NSA, the nation's largest intelligence agency, unless it gets permission to do so from the Foreign Intelligence Surveillance Court."
